URINAL.

SPECIFICATION forming part of Letters Patent No. 751,976, dated February 9, 1904.

Application filed March 19, 1903.

To all whom it may concern:

Be it known that I, DAVID CRAIG, a citizen of the United States, and a resident of Melrose, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Urinals, of which the following is a specification.

My invention relates to urinals; and its object is to provide an improved urinal of simple construction capable of being quickly and easily installed and removed.

Afurther object of my invention is to provide an improved and simplified wall-plate for supporting the urinal-bowl.

Heretofore urinals of the class to which my invention relates have been so constructed as to require the use of fastenings and supporting devicessuch as bolts or screws of more or less elaborate character, as well as of screwcouplings or the liketo effect the pipe con nections, all of which require careful manipulation and adjustment when the urinal is installed or removed for the purpose of repair or other reason. Furthermore, the rust or oxidation of these fastenings and fittings and their tendency to accumulate dirt not only renders the urinal unsightly but unsanitary.

By the use of my invention the employment of the usual fastenin gs and supporting devices is dispensed with, the bowl is supported by the pipe-couplings alone, and the couplings are of such construction that they require no other manipulation to effect a union than the setting One member of each pipe-coupling is secured to the bowl andthe other to a fixed support, so that the urinal may be installed or removed simply by lowering or raising the bowl. The fixed support is preferably a wall-plate of cast metal and of novel construction presently to be described.

In the accompanying drawings, Figure 1 is a central vertical section of a urinal embodying one form of my invention. Fig. 2 is an elevation of the rear side of the cast-metal wall-plate hereinafter described.

Having reference to the drawings, A represents the bowl of my improved urinal,which may be made, as usual, of porcelain. Through the bottom of bowl A is provided an exhaust Serial No. 148,515. (No model.)

or discharge opening a, which is continued for a short distance below bowl A by a short integral section of pipe (0. The top edge of bowl A isbordered, as usual, by an integral flushing-pipe a perforated along its under or inner side. At the top of the bowl pipe (1, communicates with a chamber a Through the bottom of chamber a is provided a tapered opening a, within which is firmly fixed the end of a coupling member (0 whose lower end is made up of a plurality of concentric rims a. The member 0, is adapted to telescope with a similar opposed coupling member a, fixed to the end of a section of pipe a and when in en: gagement therewith the rims of one member are intermeshed with the rims of the other. By filling the spaces between the rims of the lower member with a fluid the joint is effectively sealed. For a more detailed description of the construction of the union and of the principle of operation of the seal thus effected I refer to my patent for Pressure-resisting seal,No. 7 25,937 dated April 21, 1903. The flushing-pipe a is suitably secured to the back plate B. It will now be clear that with one of said coupling members fixed to the bowl and the other to a support the two may readily be slid together or apart bymoving the bowl vertically. A similar coupling and seal may be effected at the bottom of the bowl connecting the duct a, leading from the dischargeopening of the bowl, with the waste-pipe a". The concentric walls made up of the end of pipe and rim a intermesh with the walls or riins a and pipe end a, forming with the use of a suitable sealing fluid a union of the same character as above described, the two members of which maybe engaged and disengaged by moving the bowl vertically, as above described with reference to members a and 60 The two couplings above described not only form sealed joints, but hold the bowl in place, the lower one preferably holding the weight, while the upper one prevents any forward or lateral pitch. 7

The supporting-plate B is preferably a wallplate of cast metal and -is supported at the proper height by standards 5. It may be secured in position against the wall in any suitable manner. The pipe a may be integral with plate B or affixed thereto and projects from the front face of the wall-plate B, serving not only as a pipe connection, but as a shelf for supporting the bowl A. At its inner end the pipe a communicates with a conduit 6 upon the back of and cast integrally with plate B and provided with a trap or siphon 6 as shown. From the trap the conduit extends to the lower end of the plate B, at which point it may be connected with a pipe leading to a sewer. Plate B is also cast with a horizontal ventilating-conduit 6 Leading from conduit 6 below the siphon Z2 is the conduit 12*. The conduit 6 may communicate with any suitable plumbing-trap vent-pipe in the building. By arranging the conduit 6 horizontally a number of plates B may be set up side by side and connected in series by simply connecting the proximate ends of the conduits 6 It is customary to face the wall of the room in which the bowl is mounted with a slab or slabs of stone and to mount the bowl upon the outside of this facing, and my invention, as herein illustrated, is adapted to such construction of wall, 0 representing in section a slab of stone, and D the wall of the room. The top and bottom edges of the plate B are each formed with a leg 6 and these legs serve to space the'slab C from wall D. The plate B may be held in position against the wall by any suitable fastenings, such as bolts, L-shaped hooks, or iron straps.

At the top of bowl A is provided a ventilating-outlet E, which registers with the end of a ventilating-pipe 6 when bowl A is in position.

The telescoping coupling connecting the two flushing-pipe sections a and a is preferably made longer than the coupling connecting the two discharge-pipe sections a and a, so that in placing the bowl in position the pipe-sections (0 and a may be first engaged and then the pipe-sections a and a, which will be found of material assistance in installing the bowl. Furthermore, the long coupling in the flush ing-pipe will furnish a seal of high-pressure resisting capacity.

It will now be observed that an exceedingly small amount of piping and pipe-fitting is required, that the bowl A maybe readily installed and as readily removed and replaced without any other labor than that of lowering or lifting the bowl when necessary, and that the bowl is supported by the wall-plate B and not, as heretofore, by the stone slab, in which case special and separately-manipulated fasten-ing devices were required. The advantages derived from these structural features will be obvious to all skilled in this art.

In the drawings the section a of the discharge-pipe is shown as made in two parts; but this is not material and is simply for convenience in assembling where the stone slab C is to be used between plate B and the bowl A. Obviously it may be made all in one piece in cases where the slab C is omitted.

What I claim is 1. In aurinal, a bowl; 2. support therefor; a flushing-pipe and a discharge-pipe each made in two sections, one section of each pipe being fixed to the support and the other section of each pipe being fixed to the bowl; two vertical couplings, one for each pair of pipe-sections, the upper member of each coupling being fixed to the pipe-section on the bowl and the lower member of each coupling being fixed to the pipe-section of the support.
